You have me beat seven ways from Sunday on the Infomania - and underestimate your own abilities at interpreting and analyze-ing. That Tensegrity trellis is an example - understanding the core of it, intuitively, and being able to modify it.

Really do look forward to some pics of it. In progress pics would also be very welcome.

Was able to get about half-way through that Chinese 'summit' article. The author nails it. That is what slowed me down to a crawl, too much thinking about all the ways in which he has accurately analyzed the situation, and communicated it clearly.

Recently, someone who only knew me for a couple of visits - said "You think things too much." More truth to that than is comfortable admitting.

Tensegrity torus...

thanks for the muy excellente setup of the high horse podium.

My pleasure, mon. This is what an infomaniac does. I'm not really qualified to interpret/analyze some arcane information, but I am quite proficient at finding it. I can't be expert at everything (as much as I would like to be), but I do know where and how to look.

I dismantled my first tensegrity bean trellis as it was simultaneously too complex and too dull (a simple arch). Revisited Bob Burkhardt's work and found the perfect base structure. Bob shows a 12-stage tensegrity torus composed of alternating 3-strut tetrahedra. Two long struts/one short, then two short struts/one long.

You can find it on the pulldown menu here on his tensegrity viewer:

I'm modifying the design slightly by opening the torus and adding another loop (or maybe two) so it will look like a giant spring. Using 3'x3/8" fiberglass rods as struts and 17 gauge galvanized steel wire--electric fence stuff. Pix when it's done.
